Wow, that's different!

Is that a quasar? Or weird lens?

Definitely a weird one! The orange core looks the same color as the bigger galaxy at 1 o’clock, so perhaps at the same redshift (~0.3 from SDSS). But it looks like a perfectly face-on, undisturbed spiral (which I wouldn’t expect if it were interacting with that bigger neighbor)! It looks too perfectly centered to be a chance superposition, and too thick to be lensing. I’m stumped!

It could be an intermediate stage leading to the formation of a ring galaxy like Hoag’s Object perhaps? I’ve not seen many with such distinctly different cores and outer disks before (although a lot of what I thought might be lensing candidates from the DR9 data appear to be similar red+blue galaxies when viewed in HSC).
